Amino-substituted benzoylguanidines, process for their preparation, their use as a medicament and medicament containing them Benzoylguanidines of the formula I ##STR1## are described in which R(1) or R(2) is an amino group --NR(3)R(4), where R(3) and R(4) are H or (cyclo)alkyl or R(3) is phenyl-(CH.sub.2).sub.p -- where p=0, 1, 2, 3 or 4, or phenyl, or R(3) and R(4) can also together be a methylene chain, and in which the other substituent R(1) or R(2) in each case is H, F, Cl, alkyl, alkoxy, CF.sub.3, C.sub.m F.sub.2m+1 --CH.sub.2 --, benzyl or phenoxy, and their pharmaceutically tolerable salts. The compounds according to the invention have very good antiarrhythmic properties, as occur, for example, in the case of oxygen deficiency symptoms. The compounds are used as antiarrhythmic pharmaceuticals having a cardioprotective component for infarct prophylaxis and infarct treatment as well as for the treatment of angina pectoris, where they also preventively inhibit or greatly decrease the pathophysiological processes in the formation of ischemically induced damage, in particular in the production of ischemically induced cardiac arrhythmias.
描述了式I的苯甲酰基胍基苯甲酰胍衍生物的制备方法、它们作为药物的用途以及含有它们的药物。其中R(1)或R(2)是氨基--NR(3)R(4),其中R(3)和R(4)为H或(环)烷基,或R(3)为苯基-(CH.sub.2).sub.p--,其中p=0、1、2、3或4,或苯基,或R(3)和R(4)也可以一起为亚甲基链,而在每种情况下的另一个取代基R(1)或R(2)为H、F、Cl、烷基、烷氧基、CF.sub.3、C.sub.m F.sub.2m+1--CH.sub.2--、苯甲基或苯氧基,以及它们的药物耐受性盐。本发明的化合物具有非常好的抗心律失常性质,例如在缺氧症状的情况下发生。这些化合物被用作具有心脏保护成分的抗心律失常药物,用于梗死预防和梗死治疗以及心绞痛治疗,在这些药物中,它们还预防性地抑制或大大减少在缺血诱导损伤的形成中的病理生理过程,特别是在缺血诱导心脏心律失常的产生中。
